LPAR (Logical Partition) = 1 region of mainframe memory assigned to an operating system. The host is microcode in the mainframe. LPARs is the plural. It was released in the 1990s as an outgrowth of VM/ESA.
z/TPF (Transaction Processing Facility) is a very high speed operating system that spreads files across many disk volumes. Originally called APF (Airline Processing Facility). The actual compiles are done under z/OS then the object modules are transferred. IBM wrote the operating system and compilers for software but the individual companies wrote the appliction software customized for each company. Yes, errors creep into the software, but the individual sites have to verify everything works before using their final software for production (handling sales). Most mainframe software is closed source, vendor written and supported. The CBTTAPE site is where most mainframe open source programs are shared. But these are just utility programs that assist the operating systems. Without know what the bug is (I. E. Royal Bank of Scotland several day outage) it is very hard to assign blame.
